Abstract: 881,719. Lathes. PLESSEY CO. Ltd. Feb. 17, 1958 [Feb. 15, 1957], No. 5306/57. Class 83 (3). In a mechanism arranged to perform a succession of operations under the control of an electric control which can assume several controlling conditions, the control means is responsive to the completion of one operation to effect another and the operations controlled can be preselected by a selecting means. The set-up for controlling a lathe is shown in Fig. 1, the air valves being electrically-operated and the timer operating to allow for a gravity feed of a new workpiece. A sequence of operations is performed in which the turret slide is successively fed at rapid rate to drill and groove a workpiece, is then fed at feed rate to thread it, and at rapid rate again to countersink, drill and part-off. A switch operated by a pin carried on a bar-feed pusher-head operated by weights 132 stops the machine and starts an alarm to warn the operator when the stock is exhausted. The change-speed lever 101 and the spindle direction control lever 105 are operated by pneumatic means C8, C4 and C5. The airoperated chuck is controlled by a valve V10. The turret 108 is locked by a pneumatic device C1. Stops 114 are indexed with the turret to control the depth of feed. The turret slide is fed by a device C3 through pinion 115 and is associated with feed control check valves HC1, HC2. Pneumatic devices are carried by the cross-slide 122 and saddle 120 to feed front and rear tool posts. The plug-board may be replaced by a plurality of contact fingers and a common conductor co-operating with a punched card. The speed control of the lathe may be obtained by actuating a multi-speed electric motor.

Title: Improved process and apparatus for the electro-deposition of tin alloys
IPC: C25D3/60
Filed: 1939-02-20
Abstract: 525,364. Electrodeposition of tin alloys. BAIER, S. W., and MACNAUGHTAN, D. J. Feb. 20, 1939, No. 5568. [Class 41] In electrodeposition of alloys of tin, e.g., of over 30 per cent. tin with copper, nickel, cobalt, cadmium, zinc, antimony, or other metals which can be co-deposited with tin in alkaline solutions, separate anodes of tin and the alloying metal are used in separate circuits the tin anode being polarized by a coating of oxide. The oxide may be obtained by use of excessive current density in the alloy plating bath, by gradually lowering the tin anode into the plating solution with the current on, or by pre-treatment electrolytically in weak alkaline solution, by immersion in an oxidizing solution, or by heat treatment. The process being thus conducted so as to inhibit the tendency of the tin to dissolve as divalent salt instead of tetravalent, increases the coherence of the coatings. Alkali tartrates, e.g., as Rochelle salt, are added to the plating bath to improve the appearance of the alloy deposit. In an example a plating solution contains stannate, cuprocyanide, hydroxide, and cyanide of sodium, and Rochelle salts, anode current densities being up to 20 amps. per sq. feet and cathode up to 30 amps. per sq. feet.

Abstract: 1395277 Automatic process control HOWEBAKER ENGS Inc 5 Feb 1973 [13 Oct 1972] 5637/73 Heading G3N [Also in Division B1] In gas purification, wherein a pair of absorbers are operated alternately in a purge and flow cycle, the valved flow, counterflow and vent lines of the absorbers are controlled in dependence on a predetermined differential between the pressures in the absorbers during a repressurization stage in the cycle. As shown, a flow of contaminated hydrogen through an inlet 10 passes a flowmeter 12 and a valve 14 and is alternately directed by valves 16, 18, 24, 26 through absorbers 20, 22 for cleaning and then passed to an outlet 28. During a purging cycle a vent valve 30, 32 passes purging hydrogen from a regenerating absorber to a line 36 for storage, not shown, while a vent valve 46, 48 directs a low pressure counterflow of hydrogen from a line 40. The flow in line 40 is measured by a flowmeter 50 connected to a controller 52 which (i) maintains the counterflow pressure constant by control of a valve 44 and (ii) through a reference connection to a transmitter 13 of the flowmeter 12 and a counter 72 determines the ratio of flow in line 10 to that of line 40. At the completion of the purging cycle the regenerated absorber is repressurized to a differential pressure with respect to the absorber in use as determined by a unit 60 and the absorbers interchanged. The control of the purging cycle is effected electrically by a latching relay CR1 actuated by the unit 60, which directly controls solenoids 49a, 25a, 17a, 27a, 47a, 19a to change over the corresponding line valves of the absorbers, and a relay CR2 actuated by the counter 72, which energizes solenoids 33a, 31a for vent valves 33, 31 to initiate repressurization. It is stated that the electrical control system can be replaced by a pneumatic logic system.

Abstract: 1,067,591. Fuel tank pressurization systems. INTERTECHNIQUE. Feb. 10, 1965, No. 5773/65. Heading B7W. [Also in Division G1] An aircraft fuel tank pressurization system has a pressure indicator, indicating the pressure in the pressurization pipe leading to the tank, and an indicator indicating the direction of flow in the pipe. The flow direction indicator may comprise a rotary screw, or as described in the Specification, consists of a flap in a Venturi pivotable by the flow to touch either of two electrical contacts and cause either of two lamps to be lit indicating the direction of flow. These lamps may be mounted on the dial of a pressure gauge forming the pressure indicator. The apparatus is located between the tank and a control system which connects the pipe selectively to a ram air inlet or to an air outlet to maintain a constant gauge pressure in the tank. Thus if the pressure is too high, the lamps should indicate that air is leaving the tank, and vice versa if the pressure is low. If the right combination of signals does not occur, the control system should be isolated from the tank, and the apparatus may be arranged to actuate a valve to effect this, and to operate an alarm.
